SPECIFICATION forming part of Letters Patent No. 330,268, dated November10, 1885.

Application filed March 23. 1885. Serial No. 159,827. (No model.)

T0 at whom it may concern.-

Be it known that we, DUDLEY D. SPRAGUE, of California, Moniteau county,Missouri, and PEARLEY J. SPRAGUE, of Higbee, Randolph county, Missouri,have invented a certain new and useful Improvement in Straw-ElevatorsforThrashing-Machines, &c., of which the following is a full, clear, andexact description, reference being had to the accompanying drawings,forming part of this specification, and in which Figure l is anelevation or side view of our improved apparatus, showing it in usingposition. Fig. 2 is a similar view showing it in traveling position, andFig. 3 is a top view with the raddle removed.

Our invention relates to improvements in that class of elevators thatare mounted on an independent base or truck frame,whereon it ispivotally supported,and adjustable in vertical, lateral, andlongitudinalplanes.

The objects of our invention are,to dispense with the cumbersomederricks, braces, guyropes, counter-balances, and leveling devicesheretofore thought necessary and used; also, to provide novel means forsupporting, hoisting, and lowering the elevator, whereby its dischargeend is kept on a line vertically over the center of the stack at allheights of elevation; also, to facilitate its transportation bycompactly folding it low down on its carrying base or truclnwhereon itsweight is well balanced; also, to provide an improved form of hoodlocated on the turn-table at the receiving end of the elevator. Weaccomplish these desirable results by,and our invention consists in,features of novelty hereinafter fully described, and pointed out in theclaims.

Referring to the drawings, A represents a base or truck, to which ispivoted'a turn-table or frame, A by a vertical shaft, B, and between thetruck and turntable we prefer to locate a circular track, 0, for thetable to turn on.

D represents a carrier-frame, connected at its receiving end to theturn-table or frame by arms I, pivotally secured to both theelevator-frame and turn-table, so as to permit the movement of the framehereinafter described.

J J J 2 represent frames secured to the elevator-frame, one on eachside, and which extend above and below the elevator-frame, and

are provided with rollers or wheels J 3 at their lower ends, that travelon an inclined track, L, secured to and supported by the turn-table,andpreferably consisting of two rails or ways, one at each side of thetable, as shown, supported at their upper ends by posts M, extendingupward from the table, at the tops of which are pulleys N, journaled insuitable brackets, N, and over which pass ropes or chains 0, con nectedto the frames J J J and to a windlass, P, journaled in suitable boxessecured to the table. By turning'the Windlass the wheels or rollers Jare made to travel up the inclined track, which causes the carrier-frameto be raised from the position shown in Fig. 2, and at the same timemoved in alongitudinal plane for the purpose of keeping its delivery endover the center of the stack.

We prefer to arch the track, as well as incline it, for by so doing thedelivery end ofthe frame will be made to move in an'exact verticalplane, as indicated by dotted line X, Fig. 1, instead of an arc ofacircle, as indicated by dotted line X, Fig. 1. This are of a circle,

however, is so large in a full-size machine that the delivery end of thecarrier would virtually be over the center ofthe stack even if the trackwere not arched. The carrier-frame is strengthened and supported bytruss-rods T, connected or secured to it and passing over the upper endof the frame J J J. WVhen in its traveling position, the carrier-framerests at its outer part on a support, U, extending upward from the truckor base. The shaft V of the raddle of the carrier has a driving-pulley,V, connected by a belt, V running parallel with the arms Ito a. pulley,V on a shaft, .V, at the inner end of the table, and this shaft carriesanother pulley, V connected by a belt, V to a pulley, V on the outer endofa shaft, V which is also secured to the turn-table, and which has onits inner end a miter or bevel wheel, V that meshes into a similarwheel, V, on the upper end of the vertical shaft B, that pivots theturn-table to the base ortruck, and on the lower end of this shaft is abevel-wheel, V, that meshes into a similar wheel, V, on the inner end ofa horizontal shaft, V that is secured tothe base or truck, and providedat its outer end with a pulley, V, that is connected by a belt, V, to athrashing machine or other motive power. The carrier-frame can thus bemoved laterally, (by turning the table,) vertically, and longitudinallywithout interfering with the operation of the raddle.

Z represents ahood or curtain arranged on the turn-table and adapted toturn therewith. We have shown it in dotted lines, Fig. 1, and secured tothe upper end of rods Z, sliding or capable of moving in brackets Z,secured to the posts M. The curtain is open at top and bottom, and itsoffice is to receive the straw from the separator-carrier and guide itinto the elevator. The separator-carrier is preferably provided with ahood, as shown, that reaches down a short distance into the curtain. Bysecuring the curtain to the turn-table as we have shown and described itcan be slid up and down, and will not interfere with the longitudinaland vertical movement of the carrier-frame D.

Our improved elevator is intended more particularly for use inconnection with thrashing-machines, but may be used with cornshellers,excavators, &c.

We claim as our invention-- 1. In an elevator, in combination with abase or truck and turn-table,the inclined track secured to theturn-table, the carrier-frame, suitable arms connecting the frame andtable, and bearings which move on the inclined track, whereby thecarrier-frame is moved vertically and longitudinally.

2. In an elevator, in combination with a base or truck and turn-table,the arched inclined track secured to the turn-table, and thecarrier-frame connected to the table by suitable arms and provided withbearings that move on the arched inclined track, whereby it is movedVertically andlongitudinally.

3. In an elevator, in combination with a table and an inclined tracksecured to the table, the carrier-frame pivoted to the table andprovided with bearings that move on the inclined track to cause thecarrier-frame to move in vertical and longitudinal planes.

4. In an elevator, in combination with a truck and a turn-table pivotedto the truck, the inclined track secured to the table, the carrier-frameconnected to the table by suitable arms, a frame secured to thecarrier-frame, and wheels or rollers on said frame which move upon theinclined track as the carrierframe is raised and lowered to cause it tomove vertically and longitudinally.

5. In an elevator, in combination with the truck and a turn-tablepivoted to the truck, the inclined track secured to the table, the

carrier-frame pivoted to the table by suitable arms, frames secured toand extending above and a belt running parallel with said arms, a-

and below the carrier-frame, truss-rods connecting said frames tothe-carrier-frame, and rollers or wheels on the lower ends of saidframes that bear upon said inclined track to cause the carrier-frame tomove vertically and longitudinally.

6. In an elevator, the combination of the truck, the turntable pivotedto the truck, the inclined track secured to the table, posts to whichthe track is made fast at its upper end, the carrier-frame, armsconnecting the carrier-frame to the table, the frames secured to thecarrier-frame, wheels or rollers on the lower ends of said frames whichbear upon the incline track, pulleys journaled to the upper parts ofsaid posts, Windlass located at the foot of said posts, and ropesconnecting the said frames to the Windlass, the whole being so arrangedthat the carrier-frame is moved laterally, vertically, andlongitudinally, as specified.

7. In an elevator, the combination of the truck, the turn-table pivotedto the truck, an inclined track secured to the table, the carrier-frame,arms pivoted to the table and to the carrier-frame, the raddle-shaft, apulley 9o shaft'journaled on the turn-table, a horizontal second shaftjournaled on the turn-table, a bevel-wheel at the inner end of saidshaft, a vertical shaft pivoting the turn-table to the truck,bevel-Wheels on the upper and lower 5 ends of said shaft, and ahorizontal drivingshaft journaled to the truck and provided with a bevelgear-wheel at its inner end, the whole so arranged that thecarrier-frame can be moved vertically, horizontally, and longi- 10otudinally without interfering with the operation of the raddle, as setforth.
